Wang Yazhi's true thoughts were this. From her perspective, both Ling Tianya and Ruan Zeyan were still young. It didn't matter whether the firstborn was a boy or a girl. At the end of the day, the child is a Ruan child, so she would like the child either way.
However, from the perspectives of the other madams and ladies, the child in Ling Tianya's stomach was probably a girl. No baby had been born into the Ruan Family for many years, so there were many pairs of eyes fixed on Ling Tianya's stomach. If it was a boy, then he would be the heir of the Ruan Family.
Ling Tianya had probably found out that she was carrying a girl a long time ago and was afraid that if the Ruan Family found out, they wouldn't want the child or would make things hard for her.
